,TELEPHONE CABINET AND SUPPORT;

SPECIFICATION forming part of Letters Patent no. 622,412, dated April 4,1899 Application filed February 11, 1898. Serial No. 669,914. (Nomodel.)

To all whom it may concern: I

Be it known that I, PAUL W. BOSSART, a citizen of the United States,residing at Marietta, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inTelephone Cabinets and Supports; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The chief objects of this invention are to provide for the convenientremoval of the working machinery from an inclosing case and to adapt thetransmitter-support to be turned and adjusted so that the mouthpiece maybe presented wherever needed.

To this end the said invention consists in the combination of aremovable part of a tele-' phone-case with the operative mechanismattached thereto and with the body of the said case, also in thecombination of a transmitter with its support, which is adapted to beadj usted and turned into any desired position and which may be attachedto the said telephone-case, also in the construction and combination ofdivers details hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a perspective view ofa telephone case or cabinet and attached parts embodying my invention,the front having been removed.

Fig. 2 represents a similar view, the operative mechanism having beenremoved. Fig. 3 represents a detail view of the operative mechanism andthe removable part of the case to which it is attached, the same beingshown in front elevation on a larger scale. Figs. 4, 5, 6, and 7represent detail views, in plan and front elevation, of certain electricconnections, also enlarged. Fig. 8 represents a detail view of theadjusting devices for the transmitter.

A designates the body of the telephone case or cabinet, having its backextended upward 'to form a raised wall A. A fixed horizontal partition Adivides the interior thereof into an upper compartment'A and a lowercom-" strip. Each of these contact-plates has a.

threaded stud b, (which may be, a filisteredhead machine screw,)projecting from its front, also binding-screws b for wires 17*, leadingto the necessary electrical connections.

. A removable frame or slide 0 rests at one end on the bead a. Itconsists of a horizontal part and a vertical part 0, the latter form ingthe other side wall of compartment A and resting on the partition A justoutside of the bead a, which prevents it from being moved inward toofar. This removable an gular slide or frame thus constitutes an easilydetachable part of the case. It is provided on the exterior of itsvertical wall 0 with the usual gravity-hook D, supporting the receiverE, and also with the bell F, the alarm mechanism G being attached to theinner side of the said vertical wall. To the under side of thehorizontal upper part of the said removable frame or slide I secure amagneto-machine H. In the lower compartment A is the battery I.

The horizontal upper part of said removable slide or frame is providedwith contact plates or clips 0 having hooks 0' formed on them, which arerespectively arranged and adapted to catch on the studs 1) ofcontact-plates B when the said slide or frame is moved a little to theleft from the positionshown in Fig. 5

into the position shown in Fig. 6. Each of these plates 0 is providedwith a binding screw or post 0 for the attachment of a wire J, leadingto the magneto-machine, bells, and gravity-hook aforesaid.

The wires b of plates B are connected in any suitable manner by thenecessary conductors to the line, the battery, the transmitter, and thereceiver, so that when the removable slide or frame 0 is in its placeand the contact-plates B and are engaged, as aforesaid, the workingmechanism attached to the said removable frame will be in properelectrical connection with the battery transmitter and receiver, theselast three elements or devices being attached to the main body A of thecase or cabinet. To provide for conveniently and detachably securing thesaid removable slide or frame to the body of the case without usingadditional devices, I slightly screw out the studs or screws 1),permitting the engagement of the hooks c therewith, as described, andafterward tighten these screws again, so as to bind the plates B and Csecurely together. Thus the said plates, with their books and screws,become fasteningelips for the removable part of the case and itsattachments.

The induction-coil ease K of the transmitter is attached to the raisedrear wall A of the case and provided with a lug K, to which the bent armL of the transmitter M is pivoted on a bolt orpintle 0, allowing to thesaid arm a rotary movement through a half-circle. The boss L of the armis recessed at Z to contain a semicircular spring or its equivalent N,one end of which is attached to the lug K of the coil-case, the otherend being at tached to the said arm within the said boss in such mannerthat it will operate to hold the said arm upward. lVhile the arm is inplace, the lug K closes the outer side of the recess land protects thesaid spring. The bolt 0 is provided with a nut O and passes through abrake-disk P on the opposite side of the said boss. By the said nut thesaid bolt is made to draw this disk against the said boss to a greateror less degree, whereby the augmented friction may be used to compensatefor any weakening of the said spring incident to continued strain andwear. The transmitter M, attached to the outer end of this arm, has thusa partial vertical adjustment, and the curved neck R, supporting thetrumpet-mouthpiece S, has a horizontal adjustment, as shown in dottedlines, Figs. 1 and 2. By the above construction of the supporting partsthe transmitter may be raised and lowered and the mouthpiece turnedhorizontally, so that the telephone may be placed in the corner of aroom or in any other place which might otherwise be impracticable orinconvenient, for the mouthpiece may be easily turned out of suchcorneror place to reach the mouth of the user.

These improvements are of course applicable to any kind of transmitterwhether used with the ease or cabinet or not; but there is an obviousadvantage in utilizing the case as a support for the transmitter in theordinary way.

I do not claim any novelty in the battery, the magnetomachine, theringing mechanism, or the receiver. Any ordinary forms of devices foreffecting the same general results may be substituted.

The removability of a part of the ease or cabinet and the operatingmechanism attached thereto greatly facilitates inspect-ion and repairand allows any part which may be out of order to be taken from the darkcorner where the telephone is most likely to be found into brighterlight for such purposes.

Moreover, the removable part of the instrument may be exchanged at oncefor another in good Working order, so that the interruption oftransmission is reduced to the least possible time.

These improvements will save considerable expense and trouble to theinstalling company and annoyance to all concerned.

The braking-disk hereinbefore described is preferably of brass andshould have some resiliency to insure proper mechanical and electricalcontact.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In combination with the body of a telephone-case,a removable slide orsliding frame forming part of the said case and consisting of ahorizontal part and a Vertical part or wall, the operative mechanismbeing attached to the said removable part so that it may be removedtherewith substantially as set forth.
